The general consensus of opinion seems to be that if you are going to use
"machine" modes, BPSK has considerable superiority over any form of slow CW
for the kind of very weak signals often encountered on the LF bands.
When you say "machine" modes, are you meaning CW decoded by software or
by the brain (be it aurally or visually) ? There is a profound difference...

I agree, visually decoded CW is NOT a machine mode; the final decoding
being done by the operator eye-brain, instaead of ear-brain.
I found it fascinating for that reason; you have to add some operator skill.
BPSK is a real machine mode; somebody talks about having a large bell calling
him when AFRICA locks on a signal. I see no interest in this, except for
propagation studies. A QSO obtained trying day after day, by previous schedule
and so on, is more rewarding to me.
